1 Basic Information about the Software Concept GeB E System 78
1.1 Introduction
The primary function of this software manual regarding the standard GeB E System 78 (a software
version for operating GeB E thermal printer mechanism controllers) is, to give the user technical
knowledge for understanding and implementing the functions that are accessable, so that the
controller can be put to optimal use in any application.
Through the controlling host , driver software control sequences instruct the printer to print text,
graphics, or bar code in an appealing layout on thermal paper. The software has a series of print
commands available.
Conditioning Commands help to adapt the printer to multiple application parameters. They set the
way that the asynchronous data entries such as interfaces (serial, I R, S PI,programming interface),
sensors (keys, paper end sensor P E, remaining paper sensor N P E, paper removal sensor AUX,
temperature sensor at the print head, temperature sensor at the battery), selection signals
(through jumpers and DI P switches) and wake-up signals (alarm register of the clock) affect different functions from the outside. Some of these commands can be affected and used through the
GeB E-OPD Menue® by operating the keys and with feedback from the printer (see operating manual S MAN-471).
Some of the controllers are equipped with extensive power management hardware , allowing very
efficient printing with the energy that is available. Especially, if a printer is portable and battery
operated, the IDLE mode as well as the power down modes SLE E P mode, and P OWE R -OFF
mode play an important roll. The controller is adjusted to these functions with adjusting measures
in the hardware, but also with conditioning commands that affect the firmware. In addition, there
are commands for changing the maximum power consumption during printing that can be used
to adapt the printer to the capacity of the system power supply. Parameters for the charge control
can be adjusted for Ni M H as well as for LiION battery cells.
For some applications, the current status and error messages that can be sent through the interfaces may be quite important. They report, for example, that the paper supply is running low
(N P E), or that operating parameters like the print head temperature of the operating voltage moved outside the recommended limits. Also, so-called synchronizing characters can be inserted
into the data stream that is to be processed. When these characters reach the end of the print
buffer as part of the stream of commands processed by the controller (all previous commands
have been executed), they trigger a message through the interface, so all superordinate actions of
the host can be synchronized with the printing progress.
All these adjustments are either made through hardware settings (at the factory or through switches and jumpers), through software changes during the initialization phase of the controller after
a hardware reset (e.g. during power-on), or "on the fly" through adequate integration of conditioning commands in the data stream during operation.
The highly flexible GeB E controller functions are largely achieved through the concept of processing commands in programmable batch files (text files) .
These batch files can be retrieved for processing through a key stroke, power-on R E S ET, through
the interface with special commands in the data stream, or through the final command from a different batch file. Nearly all commands that can be sent through the interface to the controller can
also be written into a batch file (E E P R O M). Whenever this batch file is retrieved, the control commands retained are integrated in the data stream, as if they were coming from the interface. This
way, text, graphics (logos), as well as adjustments, messaging and hardware control commands
that are in batch files can be processed by the controller via command.
Batch files can be kept in two memory blocks of the controller: They can be stored in the fixed
R O M (flash) of the µ-processor chip by the manufacturer. This can be done through the batch file
TINIT, which performs the basic conditioning of the controller after a hardware R E S ET. On the
other hand, the user can store the batch files in a serial E E P R O M, i.e. the user has the option to
load batch files that were programmed through the interface into the E E P R O M. This allows him
for example, to overrule the TI M IT in the flash with his own initialization batch file, thereby setting
and starting the controller with a custom condition. Depending on the size of the E E P R O M , personal logos of the user or comments may be filed in it as well, and printed out on command.
The same technology is used for setting the operating parameters through the GeB E -O PD- Menue® that is controlled with the operating keys on the console (OFF/N EXT ; FE E D/ENTE R). U sing
the printer as a feedback display, the user can change the operating parameters of the printer.
The firmware program behind the menu manipulates a batch file stored in the E E P R O M out of
which the conditions of the operating parameters are performed.
This menu can also be used for setting the clock. If the appropriate batch file is available, instructions for operating the menu can be accessed. Furthermore, the printer can be controlled in a
H EX dump mode from the menu (or through other manipulations). In this mode, the data stream is
no longer interpreted for its command content, but only the hexadecimal content of the complete
GeB E E+F GmbH • www.oem-printer.com • GeB E Doc.No. So MAN-E-485-V1.5 • GeB E-System-78 • page 7 of 60
data stream is printed. This mode can be very helpful for diagnostic tasks, mainly during service
at the print system. The S ELF TE ST feature, which can be accessed with the F E ED button during
power-on, can also be very useful.
In order to give a quick idea, which parameters can be conditioned by the user, which print
commmands are processed, and which additional functions are provided by the software of the
controllers for the user to solve his print job, the following chapter has a list of all the options in
note form.
1.2 List of Possible Conditionings of the Controller
1.2.1 Which Functions of the Controller are Alterable?
• Interface parameters: baud rate, data bits, parity, stop bit

Note:
If the DI P switches 2 and 3 closed, wh i le 1 and 4 are open, the Ge B E-O P D Menue®
wi l l be active, and the DI P switches wi l l be di s abled.
2.1 Initialization Values after a Reset - (Software DI P Switches)
The flash memory of the µ-processor contains an initialization batch file "TIN IT" that holds the
commands for initializing the controller. If the printer is required to e.g. print with double height
and inverse in data mode, the corresponding commands are set into the text file TINIT. After a
R E S ET, the controller will first process these commands. Virtually all commands can be entered
in a batch file. The controller will interpret the retrieval of a text file, as if data and commands are
sent through an additional "virtual" interface. A batch file can contain the command for retrieving
another batch file at its end. If an optional E E P R O M is available, the user can change the TINIT
through an interface. Please also refer to the chapter E E P R O M in Commands for Working with
Batch Files on page 47. After a hardware R E SET, the standard settings are activated first. Next,
the TIN IT is processed. If the TINIT is in the E E P R O M , the one in the flash is ignored.

The firmware analyses the settings of the jumper and the DI P switches. Afterwards, the TINIT filed
in the flash, or preferably the one in the E E P R O M is processed. If the line feed key is still held
down at the end of TINIT, batch file T0 will be retrieved next. T0 is mainly intended for the printing
of a batch file containing text (potentially in conjunction with a logo) as a kind of self test with "advertising".
For general possibilities and information on the handling of batch files, please refer to Batch Files
(Text Files) on page 46.
3 Conditioning of Interfaces
3.1 General Information
While the data formats are automatically controlled with the serial interfaces with protocol (U SB,
Bluetooth, GeB E-I R, H P -I R, IrDA), the baud rate of the serial R S232 can be adjusted by command
or through the GeB E -OP D- M enue®.
The serial interface transmits print data to the printer and the feedback of status information back
from the printer. These data flows are controlled through a simultaneous hardware and software
handshake.
Due to the available baud rates, a handshake is not carried out after each character, since the controller is able to manage all characters in the buffer memory without any timing issues. The input
buffer has a 255 byte memory. Since many hosts cannot imediately stop the data stream, a handshake is carried out before the input buffer is completely filled. Whenever the memory is full except
for 223 characters, the controller will switch the CTS line to stop and send the control code <Xoff>
through the serial data line to the host in order to stop the data stream from the host to the controller. Afterwards, when the buffer has been emptied except for 32 characters, the controller will deblock the CTS line (level change) and send the control character <XON> through the serial data line
to inform the host that more data can be transmitted.
For the data transmission from the printer controller to the host, the handshake method is not used
at all, because the controller only transmits short sequences with a data rate that is relatively low
for the host. Therefore, it can be assumed that this data is directly received by the host without
loss.
Hardware Handshake
During the hardware handshake, the transmitting data source (host or printer controller) will usually
recognize from the voltage levels on the hardware lines, whether the opposite side is ready to receive data or not. In this case, however, the feedback line is not observed during the transmission
from the printer controller to the host. Whenever data accrues, it is immediately sent to the host
through the serial line.
During data reception, the printer controller controls the handshake line CTS (clear to sent) in connection with the monitoring of the complete input buffer. The signal is practically controlled simultaneously with the software handshake (<XON>/<XOff> protocol) that is performed through the data
line.
Xon/Xoff - Protocol
Parallel to the hardware handshake, the data transmission from the host to the controller is also
controlled through the Xon/Xoff protocol. Which one of the two procedures is used to control the
data stream is decided through the options and the settings of the host software.
3.1.1 Format of the Serial Interface
The illustration shows the bit pattern of a serial character.
One character consists of:
start bit: 1
data bits: 7 or 8
parity bit: odd, even, non Image: Data Format of the Serial R S232 Interface
stop bits: 1 or 2
Attention!
When the printer is operated at an extremely slow
speed (<5mm/sec.), special settings may be necesary. Please contact our
technical support for information in this case.

Configuration of the serial interface
The controller switches to the new baud rate as soon as the preceeding
characters have been decoded and transferred to the printer mechanism.
This may lead to a delay for the execution of the baud rate command, causing the old setting to remain active for some time.
Therefore, it is important to use this command only, when the controller is
not busy. This is the case after a reset, or it can be inquired with the feedback of a synchronizing command (see Chronological Synchronization with
Other Devices).
Authorized values for [baud rate] (binary):
1 : 1,200 Bd , 2: 2,400 Bd , 4 : 4,800 Bd , 9: 9,600 Bd , 19 : 19,200 Bd

If the second highest bit in the mode flag is set, the following will apply:
When a parity or a framing error occurs, a "?" will be printed in place of the
defective character. In case of an overrun error, a "!" is printed in place of
the defective character, followed by an "X" sent through the serial interface. The standard version has the printing of "?" as a result of a framing
error disabled.
After a R E S ET, the DI P switches are scanned, and the baud rate is set accordingly. If a different setting is to be selected automatically after the R ESET, it has to be entered in the TINIT.
The transmitter of the serial interface will also be disabled at first in order
to prevent messages from being sent in a baud rate other than the one selected.
The command <ESC> "]" $00 $00 will then turn on the transmitter of the
serial interface without changing the current parameter settings.
This command is filed at the end of the TINIT in the flash. If the EE P R O M
TINIT is used, this command must be behind the baud rate command.
Through bit 7 of the M ODE flags, the output of messages through the serial interface can be disabled completely.
3.2 Infrared Interfaces
3.2.1 General Information
It is important to consider that infrared transmissions only work "line of sight". The radiation angle
is about +/-15 degrees. The transfer distance, which also strongly depends on the efficiency of
the opposite side, is about 1.0 meter. It can be expanded to < 3 meters by installing a booster-I R
LED.
Some devices will signal an I R communication through an LED.
3.2.2 IrDA Protocol
I R LPT (printer service)
I R CO M M 9 wire (optional)
Refer to: www.irda.org
3.2.3 GeB E-I R Protocol (Bidirectional)
For master-slave connections (dot to dot), the completely disclosed GeB E -I R prococol provides
the user with a simple and affordable option to integrate an I R protocol in his system.
In contrast to the IrDA protocol, the GeB E -I R protocol has no software layers that could be used
for the communication in networks or for controlling the hardware. The GeB E -I R protocol comes
close to the software layer IrC O M M of the IrDA standard. Commands for controlling printer-specific functions are also included.
See protocol description: G eB E document no.: 394- MAN-D-I R -Protokoll.
3.2.4 H P - I R Protocol (Unidirectional), only G CT-4378/79-FLAS H
See protocol description: GeB E document no.: 417- MAN-E -H P-I R.
While the GeB E -I R protocol and the IrDA protocol act bidirectionally, the H P -I R protocol only
works unidirectionally, i.e. the printer recieves print data, but it cannot send messages back (e.g.
buffer full). For this reason, the timing of the data transmission is tuned, so the printer is guaranteed to always be able to print out the data received through the H P -I R interface without the loss
of any data. The transmission speed is limited to app. 800 baud.
3.2.4.1 Operation
In the setting "IrDA "or "GeB E I R", the I R receiver will even be active in the sleep mode, so the
device will not have to be switched on explicitly for printing. The power consumption of the printer is only about 25µA in this mode. However, the printer should still be turned off during long periods of inactivity.
In the setting "H P-I R", the I R receiver is turned off during the sleep mode. Therefore, the device
has to be reactivated explicitly for printing. The power consumption of the printer is only about
18µA in this mode. However, the printer should still be turned off during long periods of inactivity.
3.3 U S B
The G PT-437x-FLAS H- U S B meets the U S B specification V1.1 for full-speed devices. The printer
is compatible with the U SB V2.0 bus systems. The U S B device class is equivalent to a "Vendor
Specific Device". Therefore, transmission can be done with virtual C O M port drivers.
The printer will operate like a serial printer. The virtual C O M port drivers are available for the operating systems Windows 98/98SE/M E/2000, and XP, and possibly WinC E from the third quarter of
2004. For Linux V2.40 and up, there is a direct Kernel support. Therefore, a VC P driver is not required. Standard GeB E printer drivers can be used.

3.3.1 Operation
Before the first operation, the matching virtual C O M port driver and the printer driver have to be
installed. The C O M settings of the virtual C O M port have to be set in accordance with the printer
settings (recommended: 115,200, n, 8, 1, XON/XOF F). If sleep mode is selected for the printer, it
will go into sleep mode after the set time period. However, the U S B interface will remain active, directly supplied from the U S B bus. A new print job with the standard drivers will reactivate the printer without any loss of data. In a U S B suspend mode, the internal U S B interface is also turned off.
The printer will 'go to sleep' after the set sleep time period.

3.4 Bluetooth®
The G PT-437x-FLAS H- BT meets the BT specification V1.1 class 2, attaining a transmission range
of about 10 -15 m. If you require a longer transimission range, please contact us. The printer can
be operated with a customary BT dongle that comes with a virtual C O M port driver.
A remote R S232 station is also available.
3.4.1 Operation
The printer responds to an inquiry scan with its name "G PT-4378/79-FLASH" and its BT address.
However, it can also be addressed directly, without a scan, with its BT address.
A "BT connect" activates the printer. The printer will maintain a connection until it goes into sleep
mode. The online power consumption of the printer with an active BT link is about 35 mA. The
sleep mode disconnects an active connection and activates the BT sniff mode. In this mode, the
printer scans its environment for possible calls every 1.25 seconds. During these inquiry scans, it
remains visible and responsive. It will then take about 2-3 seconds to establish a connection.
The power consumption in this mode is about 1.5 mA. When the printer is reactivated through the
feed button, the BT tranceiver will remain in sniff mode. After the set time period, the printer will
go back into sleep mode.
If you are not planning to operate the printer for several days, switch it off with the OFF/NEXT key.
After the power is turned on, it will take a minimum of 10 seconds for the printer to become ready
to recieve data.

Function
Print command with one line paper feed.
An immediately following <LF> will be ignored.
Print command with one line paper feed.
An immediately following <C R> will be ignored.
When the line is full, the exceeding characters will trigger a new line. The
number of characters per line is determined by the selected font and the
effective print width. With the command
<E S C> "h" n, the effective print width can be reduced to a smaller value
than the one that the maximum print width allowed by the printer mechanism.
For the standard font #1 with 16 horizontal times 24 vertical characters and
an effective print width of 384 pixels, the result would be:
384 pixels/line / 16 pixels/character = 24 characters/line
<ES C> "h" n
1B 68 n
Set the effective print width of the printer mechnaism in bytes n:= {16
...max. print width of the mechanism}.
This command only works for text printing. It can be used to change the
maximum number of characters per line. It is printed with left-side justification.
<ES C> "V" "X"
B 56 "X"
Print and report synchronizing character "X" through the serial interface.
If the line buffer is not empty, this command will also initiate the printing of
the current line.
String length
exceeds a certain number of
characters
Besides the code for printable characters, a large number of control codes
can be written into the 256-bytes character buffer without triggering the
printout of the next line. This could result in a blockage of the printer. Therefore, the printing of a line will be initiated, when the data string for its

This command can only be given at the beginning of a line and will be ignored otherwise. Eight dot lines will be added to each reverse paper feed. Afterwards, the printer will feed the paper forward for eight dot lines in order
to eliminate the gear play.
ATTENTION! The paper must not be transported so far, that its end leaves
the transport roll. Otherwise, the rubber roll will not be able to transport the
ejected paper forward again.
This command should not be used in combination with a paper rewinder,
since the rewinder pulls forward, while the paper is transported backwards.

n is a factor between 10 (lighter) and 100 (darker).
In general, 25 is the default value.
Values outside the range will not change the current setting.
After each R E S ET, a value that is adjusted to the respective printer mechanism is set. If different values are required permanently, they can be achieved by setting this command in the batch file TIN IT-F (at the factory) or in
the TINIT-E (by the user, if an EE P R O M is installed).
4.3.4 Graphic C ommands
The data structure of the graphic data of these modes corresponds to the commands of the P CL
specification from version 3 on . They are compatible with the M S Windows compression procedure.
The processing of compressed data takes about as much time as pure bit map printing. As a result of the smaller amount of data that has to be transmitted, there is a clear advantage in speed
compared to the process without compression (about a 1:3 ratio).

<ES C> "g" n
[DATA]
1B 67 n
1 : R un length encoded
g1....gn
n := number of bytes following
Run length interprets graphic information in byte pairs.
Each first byte is the repetition count byte for the second byte. A 0 for the
repetition count byte means that the following graphic byte will be printed
once without being repeated. A 1 means that the graphic byte will be printed twice. The repetition count byte has a value range of 0 - 255, which
translates into a print factor of 1 to 256. The second byte contains the
graphic information that is to be printed. In text mode, from left to right,
the dot on the very right is the LS bit. A 1 in the respective bit position represents a black dot in the line. After completing the line, the printer will
automatically return to the character mode.
2 : TIFF (4.0) Encoded
n := length of the following bytes
TIFF interprets graphic information as TIFF "pack bits".
TIFF combines features of unencoded and run length encoding.
The graphic information is preceded by a control byte. The control byte indicates (sign bit), whether the following byte is a graphic byte that is to be
repeated (up to 127 times), or whether a number of bytes follow (up to 127)
that are to be printed as bit map. A positive control byte expects bit map
information, a negative control byte (complement on two) respects a repeat
byte.
3 : Delta Row
n := length of the following graphic bytes
Delta row will pick out the bytes from a line that are different from the bytes
in the preceding line, and transfer only these differences.
If only one bit differs, just the respective byte has to be transferred. The
delta data consists of a command byte and 1 to 8 replacement bytes. The
command byte contains two pieces of information, the number of replacement bytes (bit 7 ,6, and 5), and the relative left offset of the last byte that
was changed (bit 4, 3, 2, 1, and 0). Value 31 as offset expects a following
additional offset byte. Value 255 of this additional offset byte expects
another one and so on. The offset values are added up. In text mode, from
left to right, the dot on the very right is the LS bit.
A 1 in the respective bit position of a replacement byte represents a black
dot in the line. After completing the line, the printer will automatically return to the character mode. During the printing of this line, the printer will
ignore all other commands.
M ixing of text and graphics is not possible with delta row.

• characters were put in that do not correspond with the character set of the code.
If the bar code is ignored, the characters of the string will be printed as plain text, as long as a
type with plain text has been selected. Ignored bar code without plain text will not initiate printing.
4.4 Form Control: Form Feed, TOF (Top of Form)
The printer controller has multiple commands for form control available.
There are different types of form control:
• control by paper length
• control with markers (forms and labels)
4.4.1 Control by Paper Length
The length of the receipt is entered through the command <E S C> "l" xh xl. The paper length is
then measured through the feed of the printer mechanism starting from the position determined
by this command. A sensor for paper positioning is not in use in this case. Strictly speaking, this
is not a type of form control. Therefore, a start position can be predetermined at any place on the
paper, and there cannot be any positioned form printing on the paper roll.
If less paper is printed on than the length predetermined by the command, the final form feed
command will trigger the final printing, and a paper feed will be processed, until the page length
counter reports the reaching of the receipt length. At this point, the printer stops feeding paper,
and the receipt may be cut off with a cut command.
If the length of printed paper exceeds the predetermined receipt length, the paper length counter
will automatically remain at the receipt length limit "max.", until an FF is processed. It will then
start to measure the predetermined paper length of the following receipt.
4.4.2 Control with Markers (Forms and Labels)
M arkers on the paper are recognized by a sensor (light barrier). This type of control can be done
with preprinted, infrared light absorbing markers on the print side of the paper, or with holes that
have been pre-punched into the paper. Marker control allows the use of preprinted paper, which
makes it easier to put the printer in the correct print position on the forms.
A marker, a gap, or a hole is recognized, whenever a P E of at least 3 mm length is reported.
The control for label printing works the same way, in order to be able to position the print headas
close to the edge of the label as possible at the start of printing . The gap between two labels is
used as the marker in this case.
Different sensors may be used to measure the paper position. Which sensor is used for form control is determined by the two lower bits in the flag byte of the command <E S C> "p"
[distance][flags].
4.4.3 Label Printing with Peeler
(See arrangement of the sensors at the printer (drawing) on page 26)
If the printer mechanism is equipped with a peeler, it can print labels, but also present t hem with
the support of a paper rewinder. The paper rewinder pulls the carrier paper around the peeler,
causing the label to separate from the carrier paper and to proceed straight. The paper transport
is preset by the form feed command to stop at a position, where a small area of the label remains
attached to the carrier paper at the edge of the peeler, presenting the label to the user without haGeB E E+F GmbH • www.oem-printer.com • GeB E Doc.No. SoMAN-E -485-V1.5 • GeB E -System-78 • P age 24 of 60
ving it fall off. The user can remove the label at this point. The command ( E S C _ n ) has the printer waiting before it prints the next label, until the label in the peeler has been removed.
The AU X sensor is installed at the peeler's edge. It registers the label and signals to the controller,
when it has been removed.
4.4.4 C ontrolling Form and Label Printing
In order to process and control the procedures introduced above, several different commands are
required. They are described in the table on page 27.
Three possible sensors are available for control:
• paper end sensor (P E sensor) at the entry of the printer mechanism
• near paper end sensor (N P E sensor), sensor connection J13 on the controller board,
is normally used for recognizing the paper supply coming to an end
• auxiliary sensor (AU X sensor), sensor connection J15 on the controller board,
is normally used for recognizing the removal of a peeled-off label, or for recognizing a successful paper cutting process
All three sensors can be used for form control. If the two lowest bits of the byte n:= [flags] are
both 0, none of the light barriers is selected as a control light barrier for the form feed, and a form
control will not be activated.
4.4.4.1 P aper End Sensor as Form Control Sensor
Most of the time, the internal reflexion light barrier (P E sensor) at the paper entry of the printer
mechanism is selected to control the form feed. The distance from this light barrier to the print
comb is about 10 mm. For label printing with gap control, the paper must be transported forward
about 10 mm, after the gap has been recognized by the light sensor, in order for the upper edge
of the label to be positioned directly under the print comb. This is automatically processed by the
command <E S C>"p"$14[XXXX XX01], if the control has located the gap (see page 27 with the
commands).
Since this sensor is also required to recognize the paper end during the form control, the marker
(or the gap between labels on carrier paper) may not exceed a length of 7 mm. If no paper is detected within 60 dot lines (7.5 mm), while the motor is running (marker end, end of gap), paper
end will be recognized, the printer will stop, and the message P E will be initiated. It has to be
pointed out that in this form mode, P E can only be recognized, while the motor is running. Therefore, paper that has been removed, when the motor is idol, will not initiate a P E message, if the
form control is turned on.
4.4.4.2 Inserting Paper in Form Mode
Since the printer can only recognize a P E in the form mode, when the paper is moving, an auto
paper load as in the standard mode is not possible. The paper has to be inserted manually. If bit 2
of m:= [light barrier flags] is set, the printer will switch back from form mode to standard mode
with the print head open (recognition through sensor switch "head open"). This allows an auto
load even in form mode, when the head is open. When the head is closed, the printer returns to
the form mode. Any markers during the auto load feeding will be ignored. After the auto paper
load and the closing of the head, batch file T10, which is only available in the flash, will be processed, regardless, whether the printer is positioned on a marker or not. This file contains a short
feed followed by an FF. The short feed allows the printer to determine, whether a P E occured, and
to stop further printing or form feeding if applicable. The opening and closing of the print head during operation does not trigger a form feed.

Length:= ( xh(256) + xl) x 0.125 mm sets the page length in mm. This is the form
feed length, if no light barriers are used. It is also used as the maximum feed length
(as a criterion for termination), when the light barrier is used as a marker sensor. If
no marker is reached and no gap is recognized within the set length, the feed will
be stopped.
When this command is processed by the printer controller, the beginning of the
page will be set automatically , as if it contained the command <E S C> "o" .
Form feed: Print command and line feed, until the TO F marker is recognized or the
preset page length is reached.
For an FF, the printer will feed, until either a marker (if the appropriate sensor is activated) or the preset page length is reached. If, at the time of the FF, the marker has
already appeared or the page length has been reached, the internal FF counter is
set to the new page length. Therefore, an FF either causes a feeding to the next
marker, or (if no marker appears) a feeding by a whole page length.
A reverse transport is taken into account, when the page length is calculated, even
if it goes beyond the form limits.
In the standard version, a form feed in the form mode can be triggered by pressing
the OFF/N EXT key. This key function branches to batch file T1 in the flash, which
contains an F F.The user has the option to alter this function by changing the T1 in
the E E P R O M .
Set beginning of page to current cursor position.
This command sets the internal position counter to zero.
Wait until label is removed, plus n x 25 ms
This command is usually given after a form feed command.
This command refers to the AUX light barrier, which has to be installed at the front
of the printer in order to recognize the removal of an adhesive label from the peeler
edge.
This command will only clear the printer, after the label has been removed, and the
light barrier reports "AUX- P E".
P lease note that AUX is a light barrier that uses transmitted light .
P arameter m - [distance] - represents the distance between the light barrier and
the print comb in 1/2 mm increments. (distance between internal light barrier and
print comb = 10 mm; m: = $14:= 20)

The remaining bits should be set to zero.
A form feed will initiate a search for the marker. When it is detected, the paper will
automatically be fed by the distance m in order to place it at an exactly defined position on the form.
Set marker length n in print lines: (1 line := 1/8 mm )
The default setting after a reset is 3 mm (24 lines).
The maximum length is 7 mm (56 lines).
P lease note:
This command does NOT send the length of the marker, but the length that the light
barrier detects as "black" (or a value sufficiently below this length). At the edges of
the marker, the light barrier is likely to report "paper still present" (depending on the
marker and the paper used).
4.4.4.6 Inserting Paper in Standard Mode
In standard mode (no form control), paper end (P E) recognition through the internal light sensor is
organized as follows: In order to make the P E function insensitive to disturbaces, the P E message
and the stopping of the printer are not triggered, until it has been positively recognized three times
in 25 ms intervals.

5 Error and Status Messages During Printing
5.1 Automatic Status Report
Status information that is reported back through the interfaces is very helpful for the safe operation of the printers. The serial interfaces (R S232, TTL, U S B, Ir, Bluetooth) are able to transmit the
most extensive information back (parallel interface is limited).
The status messages describe: R E SET form, head lifted, paper end; operational error at the cutter
or at the power supply, operating temperature, charging process, and battery status, etc. Operational characteristics are also collected in the E E P R O M: the amount of printed paper by the head,
operating time, number of cuts, and primarily the amount of paper used since the last paper roll
exchange.
5.1.1 Status Messages of the Printer through the Serial Interface
When a status changes or an error occurs, a single AS C II character is sent through the serial interface in most cases. This can be analysed by the host. After an error has been cleared, the appropriate small letter is transmitted, followed by an "X", if no additional error presents itself.
5.1.1.1 Periodical Output of the Current Status
With this command, the current printer status can be inquired through the serial interface.

5.2 Statistics
These functions can be used to compile a load profile for the printer in order to determine an appropriate service interval. This way, the printer can be serviced after effective loads. To monitor
the system, for example, service-relevant data can be reported through the internet.
If the length of the paper roll is known, a paper amount control can be set in the host through the
function E S C"v" "3" (read out length of paper used since last paper exchange).
5.2.1 Statistical Value Readout from the E E P R O M
Statistical variables are stored as 16 2-byte strings in the E E P R O M, so the permitted number of
writing cycles is not exceeded. The values of all 16 strings are added up. This results in a total value range of 65535 * 16 = 1,048,560, which equals app. 100 km of paper length or 12 years of
permanent operation.
)* Handshake output CTS normally reacts only to the fill level of the input buffer. However, it can
be programmed to go to "block interface" (log. 0), when an error status occurs. See Configuration

6.1 Behavior of the Dual LED
7 Initialization Commands: R E S ET and E RAS E Data Buffer
All data and commands of the 'print data stream' are processed sequentially.
The printer does not perform an interpretation of commands, when data enters the input buffer.
The data is only processed at the output of the fast FIFO input buffer, where the so-called parser
interprets the data for printing. This means for example for the R E SET command <E S C>"@" that
it is not immediately processed upon arrival at the input of the interface, but only after all data
has been processed by the parser that is ahead of it in the input buffer. The reason for this is that
GeB E gave preference to a significantly higher print speed, since the direct interpretation of data
at the interface input would greatly slow down the speed of the processor. For the same reason,
the input buffer is fairly small. In case of an error that could be cleared with a R E S ET command,
unprocessed data in the buffer would be the reason that this command can only be processed
after the error has been cleared. This circumstance has to be considered when choosing a strategy for error recovery.
The program transports the data that has to be interpreted from the input buffer to the line buffer.
From there, it is finally printed, when the print command reaches the output of the input FIF O,
and is interpreted as print start for the completely interpreted print line. However, if the command <E S C> "A" was planted in the print data stream, the data that has already been written
into the line buffer is erased.
The commands <E S C> "@"and <E S C> "A" that are desribed below can primarilly be used to increase the reliability of the data transfer to the printer, and therefore to eliminate interruption in a

Between the receiving and the processing of this command, the data in the

follow this command, before it determines the processing of the R ES ET to
be completed due to a feedback signal through the serial interface. Otherwise, data that was sent during the processing of R ES ET would be lost,

8 Synchronization with External Events
With the command <ESC> "V" "X", the print process can be synchronized with superior or peripheral devices.
As an example, an action is to be performed in the superior system, only after text that was sent
to the printer has been completely printed. However, since the printer has an input buffer, the user
would not know, when this is the case. If the synchronizing command is given subsequently to the
text that is to be printed, the printer will report this point of time by sending the character "X"
back to the host. Instead of "X", all available characters may be used in the synchronizing command, so the progress of complex program sequences can be indicated through different characters. It is recommended not to use characters that are sent as error messages by the controller.

9 Power Management
9.1 Limiting the Peak C urrent During Printing
The current peaks during printing can be limited by command from a maximum value, as a result
of the maximum number of pixels that are heated simultaneously, down to a minimmum value, as
a result of at least 8 pixels being heated simultaneously. This means, that if a lot of pixels are heated sequentially in a horizontal line, the print speed is reduced significantly. If the power voltage Vp
is high, the pixel voltage will be higher as well, since the current limiting is not realized through current measuring, but by limiting the number of pixels that are heated simultaneously.
Comm. (ASCII)
<ES C> "[" n m
Comm. (hex)
1B 5B n m
Function
Set the maximum number of pixels that can be printed simultaneously (indirectly: max. power consumption) and the print quality:
<E S C>"[" [max. number of black pixels] [max. segment size in bytes]
First parameter n:= [max. number of black pixels] determines, how many
black pixels are printed simultaneously.
The minimum is 8, the maximum is 128, default is 64 or $40.
As soon as the number of black pixels in one line segment has reached
this value, the rest of the print line is filled with zeros, and current is applied
to the line. In the next cycle, the pixels that have been printed are filled
with zeros, and then more pixels (maximum n) are heated, etc. Recommended values for n are : 8, 16, 32, 64, 96, and 128.
The maximum current I depends on the operating voltage Vp and the dot
resistance R dot:I = (Vp x number of pixels / Rdot) + IVcc + Imotor.
Example: for 64 pixels = at Vp = 5V and Rdot= 123 Ohm app. 3A
at Vp = 7.2V and Rdot= 123 Ohm app. 4.7 A.
Second parameter m:= [max. segment size in bytes]
Minimum is 1, maximum is the print width in mm, for example 48 for the
G PT-4382.
This parameter determines the print speed dynamics:
H igh dynamics means, the printer prints each line as fast as the maximum
current allows. Therefore, an empty line is printed faster than a full line. If
the dynamics is disabled, each line is printed, as if it were completely
black.
The parameter m determines,how many bytes are printed simultaneuously
(even, if they contain only zeros, and no dots are printed). If a 1 is selected, the printer will divide the line in segments of 8 pixels width. If m includes all bytes arranged in one line (for 8 pixels/mm the total effective print
width in m mm), the print line can also be heated in one cycle, if the maximum number of pixels n of the first parameter is not exceeded. An even
printout can be obtained with <ES C> "[" [32] [4], for example, because the
maximum number of printed pixels n:=32 represents the number of pixels
in the m:= 4 bytes that are printed simultaneously. High dynamics are the
result of <ES C> "[" [32] [48]: If no more than 32 dots with 48 bytes max.
are printed in one line segment, this can be done in one print cycle. However, if a completely black line is printed, multiple cycles of just 4 bytes each
are required. The print time of each line is different, depending on the blackening.
Recommended values for m are :
• for maximum print dynamics: m= max. segment size in bytes.
• for even printing: m= same number of pixels in the heated segment as in
the heating parameter (for example N:= [64], m:= [8]), always considering
the maximum peak current for Vp.

9.1.1 Power Consumption, Print Dynamics and Print Quality
This commands sets the maximum permitted peak current indirectly through the number of pixels,
the known dot resistance, and the maximum possible supply voltage Vp.
The maximum number of dots to be printed is controlled in a way that the given peak current limit
is not exceeded. This allows the power consumption of the printer to be adjusted to the capacities
of a superior supply system.
In addition, the print dynamics can be adjusted through the other parameter m, also affecting the
print quality.
9.1.2 Status Display
The "low current" status LED can be turned off by command or switched to a power saving mode.
Please refer to the command <E S C> "y" "n" in the chapter LED Control on page 31.
9.1.3 Estimating the Battery Status
Through the battery test command <ES C> "{"l m n, which causes the controller to give a feedback
to the host on some parameters that concern the battery status, the host can analyse the battery
status, if necessary. Please refer to chapter Battery Test on page 45.
9.2 Power-Down Modes
Especially for battery operated, portable devices, the power consumption of the printer plays a
decisive roll for its energy efficiency and its operational reliability. For this reason, GeB E put a lot
of effort in this area during the designing of the controllers, resulting in the power-down modes.
There are three power-down modes, however, not all three come into operation in the controllers
with the GeB E System 78. Please refer to the information on controller features in the respective
operating manual or hardware manual:
• Idle mode
• SLE E P mode
• P OWE R -OF F mode
9.2.1 Idle Mode
Whenever the controller has no more hardware tasks to work on (the print buffer does not contain
any more data for printing), it will automatically switch to idle mode. In this mode, the system uses
about 5mA current, but it is completely functional, accepting external signals (like I R Q, or data
through the interface) without delay. The handshake signals also remain in effect.
9.2.2 SLE E P Mode
Besides the idle mode working automatically, the controller can be specifically controlled to
switch from idle mode to SLE E P mode after a preset waiting period.
The SLE E P mode lowers the power consumption to a value that is considerably lower than the
self-discharge rate of a NiM H battery (< 15µA typical with R S232 interface). Consequently, the
user has the option to do without a POWE R -OFF switch by only using SLE E P mode. In SLE E P
mode, the power supply of the system remains turned on, so the contents of the register are preserved. The R S232 interface outputs of the controllers are switched to a high-ohm status. The inputs stay susceptible to signals. After reactivation, the controller can continue to work with the selected parameter settings, if it was programmed accordingly through the power-down command,
or it will go through a hardware R E SET.
9.2.3 P OWE R -OFF Mode
In P OWE R -OFF mode, the controller turns itself off completely after a time period that can be set
by command. The power consumption will then usually sink to typ. <1µA. After reactivation from
P OWE R -OFF mode, the controller always goes through the complete P OWE R -ON R E S ET initialization, losing all previously changed settings that are different from P OWE R -ON R E S ET settings.
From POWE R- OFF, the controller can be reactivated through the F E ED key, the RTS line, or by
connecting the charger.
60
9.3 Power-Down / Power-Off Waiting Period
After a preset waiting period, the controller can switch from the idle mode to power-down mode.
The command <E S C> "e" n either allows the complete blocking of power-down, or the setting of
this waiting period.
This command will not effect the other power-down parameters.
9.3.1 Attention: Switch to P OWE R -DOWN Mode only from Idle Mode!
The transition to the P OWE R-DOWN mode only works from the idle mode, so this mode has to be
switched to first. If there are print data left in the print buffer, while a paper end message is generated, the printing can not be completed. Consequently, the data will remain in the buffer, and the
idle mode can not be entered. Therefore, a P OWE R -DOWN will not be possible.
9.3.2 Initialization from the POWE R -DOWN Mode
After the controller has been reactivated from P OWE R -DOWN mode, it will go through an initialization phase. It can either go through its standard initialization, just like after P OWE R- ON R E SET,
or, coming from a SLE E P mode, preserve the parameter settings as they were set before the
SLE E P mode.
This decision can be made with the P OWE R -DOWN command (see page36).
If there is no more data in the line buffer that has to be processed, the controller will switch from
the idle mode to the selected POWE R-DOWN mode (sleep or power-off mode), after the preset
"waiting period before power-down" has elapsed.
The extended command <E S C> "e" n [flags], which is described in detail on page 36, allows the
following selections:
• blocking of power-down
• setting the waiting period
• hardware preselection applies / is ignored
• type of power-down mode
• behavior after reactivation from the sleep mode: initialize, or continue to work with the settings
that applied before the sleep mode was entere

Attention: Some errors such as paper end block the printout. In this case,
the line buffer will not become empty. These situations should be considered for the application strategy.
The individual bits in the byte [flags] have the following effect:
Permitted values for bits in the byte [flags] :

the type of power-down mode (power-off or sleep

9.4.1 Attention! Operating Voltage Feedback During P OWE R -DOWN Mode
Through the Interfaces.
The possibility that voltage is fed back through the interfaces during the P OWE R -OFF mode (even
the smallest currents can cause errors in controllers that are in power-down mode) has to be considered. Power feedback cannot occur with the serial R S232 version, but it is possible under certain circumstances with the serial TTL or the parallel interface. Therefore, high power levels at the
controller input have to be avoided, whenever P OWE R -OF F mode is used, and they have to be taken into account for component options and for the connection of adapters in conjunction with
the parallel Centronics or the serial TTL interface.
Due to the high number of connections, the chances of this occuring are much higher, if a parallel
interface is used. Therefore, the POWE R -OFF mode with a parallel interface is initiated as follows:
1. G ive power-off command, if required.
2. /Sel_In: Set to low
3. All data lines: Set to low levels
4. /Strobe: Set to low level
If problems should occur in spite of these measures, a fixed resistance can be installed on the
controller board at the factory. This resistance drains the internal operating voltage Vcc of the
controller, helping to lower it below the R E S ET threshold, should Vcc be "pulled up illegally" by a
power feedback through the connected interface. Please contact the technical service department
at GeB E.
9.5 Reactivation from P OWE R-DOWN
In contrast to the idle mode, which is always active, the controller has to be reactivated from the
sleep mode or the power-off mode through the following methods, before it can receive data
again.
• Pressing the feed key
• Sending a dummy character through the serial (R S232/TTL) interface (TxD)
• Level change at the handshake line CTS (serial) (R S232/TTL)
• Sending a dummy character through the infrared interface
• A Bluetooth "connect"
• Sending a dummy character through U S B
• G ive /strobe pulse (parallel interface adapter)
• Sending a dummy character through the parallel interface
• Applying a charging voltage
After reactivation, the controller will go through an initialization phase of about 30 ms. During this
time, no data may be sent to the controller, since they would be rejected. The data may be sent
only, after the controller has reported ready (handshake signals are set for possible data reception,
<Xon> and/or "R" for R E SET have been sent back through the serial data line).
If the P OWE R -OFF mode was selected, the controller initializes itself after each reactivation, going
through a regular P OWE R -ON R E S ET.
Part of the standard initialization of the controller is the command <E S C> "e" $05 $02 (see page
36) that determines the conditions for the next power-down. In the standard setup, the controller
will switch from idle mode to power-down mode about 5 seconds after the last activity as a result
of the power-down command given in this form. Which power-down mode the controller is switching to, is determined through the P OWE R-DOWN jumper (special component).
9.5.1 Reactivation with the Feed Key
For reactivation, the feed key only needs to be pressed briefly - even for the power-off mode, 3ms
are sufficient. If the key is held down longer than about 2 seconds, the printer will start with a test
printout, after it has been reactivated from any type of power-down mode. The content of the test
printout is predefined with the batch file T0. See Batch Files (Text Files) on page 46.
60
9.5.2 Reactivation through Data Line TxD of the Serial R S232/TTL Interface
The most secure way to reactivate the printer controller from sleep mode is by sending printable,
individual dummy characters in > 50ms intervals,until the printer controller changes the control
line CTS or sends the software handshake character <XOn>.
9.5.3 Reactivation through RTS (CTS) of the Serial R S232/TTL Interface
In order to put the controller down, RTS has to be at < 0V (logic 1; (inverted logic for R S232
levels). For reactivation, RTS has to increase to > 5V for at least 3 ms, before it may be set back.
Attention:
When the printer is in a power-down mode, the host will receive the status message "printer not
ready to receive" through the handshake line RTS, since the interface drivers are turned off. For a
reactivation with dummy characters, this message has to be ignored by the host. It may be helpful
to use the <XON>/<XOff> protocol, since the controller will not send an <XOff> while in power
down, and therefore, will not interrupt the data stream. The host determines the state of the printer and is aware of it.
However, if a continous string of characters is used for reactivation, and the user characters are
attached without any delay, incorrect characters and/or framing errors have to be expected. After
the transmission of the dummy character and the feedback of the initialization being completed (<
Xon> / "R"), there has to be a pause of at least one character period, so the receiver of the printer
can synchronize with the beginning of the first user character (at 9,600 baud, 8 bit, no parity, 1
stop bit, the character time is about 1.05ms).
9.5.4 Reactivation through the I R Interface
Since the I R receiver has to be active, a reactivation with I R reception is only possible from the
SLE E P mode.
The request packages that are sent by an IrDA or GeB E-I R protocol at the beginning of a data
transfer replace the transfer of a dummy character.
9.5.5 Reactivation through Dummy C haracters through the Bluetooth Interface
When the printer is in idle or sleep mode, it will seem "active" on the Bluetooth network to the outside. A "connect " will reactivate the printer on time , so the transmission of a dummy character
will not be necessary.
9.5.6 Reactivation through Dummy C haracters through the U S B Interface
When the printer is in sleep mode, dummy characters have to be sent for about 10 ms without interruption in order to bridge the power-on time.
The standard Windows driver transmits dummy characters before the start of each document.
9.5.7 Reactivation from the Sleep Mode through Centronics / Select-In
The first character (positive flank at /Strobe) reactivates the controller. If a reinitialization was selected to be performed after the reactivation (default setting), this character will be rejected. For
this reason, the reactivating character that is transmitted before the print data should be a dummy
character ($00).
9.5.8 Reactivation from the P OWE R -DOWN Mode through Centronics / Select-In
In contrast to the SLE E P mode, where the power supply is active, controlling though the POWE R DOWN M ODE with a connected interface may result in power feedback through the interface to
the controller.
In order to put the controller to sleep and to prevent a power feedback of internal supply voltage
Vcc through the data lines at the same time, a dummy character ($00) has to be sent. Afterwards,"Select In" has to be set to low. Optimally, /Strobe should also be permanently set to low.
60
9.5.8.1 Attention: /Strobe=Low Sets Busy to High
/Strobe=low sets the busy exit directly to high (hardware!).
For reactivation "Select In" has to be on high for at least 3 ms, before it may be reset again.
9.5.9 Note: Reactivation from a P OWE R -DOWN Mode Through Centronics/Select-In Under M icrosoft Windows®
As a select signal from the controller, the host gets its own /auto-LF signal reported back (Connect the appropriate jumper to the serial interface.). Without an active select signal, M icrosoft
Windows® would not dedicate the printer as connected and create a time-out message after a
certain observation period.
9.5.10 Reactivation by C onnecting the Charger
Applying or disconnecting the charging voltage will reactivate the controller. If the printer detects
a charging voltage after being reactivated, it will stay turned on in order to be able to monitor the
remaining charging process.
60
10 Battery Charging Circuit (Software Control) G eneral Information
For applications with battery operation, the controller has a charging circuit supported by the processor. The behavior of this charging circuit and its monitoring can be controlled through the
charge command (see page 42 ).
10.1 Start of the Charging Process with a Formatting Charge
The battery charging equipment consists of a hardware component and the charge regulating
software that is filed in the µ-processor.
When the charging voltage is applied, the hardware will first check the charging status of the
battery. If the battery is found to be overdischarged, the charging cycle will start out with a battery-saving formatting charge (the charge indicator remains off). Once the battery voltage required
for fast charge is reached, the controller takes control over the charging process and activates
the fast charge.
10.1.1 Indication and Inquitry of the C harge Status
Each status that the charging circuit is in is indicated by the status LED through different flash
patterns. When the status is requested by command, feedbacks are sent through the serial interface.
See chapter Error and Status Messages During Printing on Page 28.
Also refer to Battery Test on page 45.
See hardware manuals of the individual devices.
10.2 Ni M H Charging C ircuit (Standard Component)
A detailed description of the controlling charge command can be found on page 42.
10.2.1 No Separate C urrent Limiting of the Charging C ircuit
The charging is managed by the processor of the controller. A few special controller versions have
a charging current control on the board that allows charging from a fixed voltage (power supply
unit 8 - 28 V) or from car batteries (12V or 24 V).
Some controllers (mainly low-cost) from GeB E are equipped with a NiM H charging circuit without
a limit to the charging current. The charging current is limited through the appropriate GeB E charger, therefore:
10.2.2
ATTENTION: Only use the matching GeB E charger!
A fixed voltage power supply unit without defined current limits must never be used for charging
NiM H batteries. Always use the appropriate GeB E power supply unit, or contact us for more information.
The standard charging parameters filed in the flash memory are tuned to certain types of batteries. Please refer to the hardware manual.
10.2.3 End Criteria for Fast Charging of Ni M H Batteries
The controller will finish fast charging and switch to trickle charging, as soon as one of the following conditions is met:
• end-of-charge through timer
• minus delta- U recognition
• maximum U recognition
• delta-T recognition
• maximum T recognition
10.2.4 Limiting the C harging Time through a Timer
If the charging currents are very low, the necessary end-of-charge cannot always be achieved by
recognizing the drop of the cell voltage (minus delta- U). Some modern Ni- M H batteries allow a timer-controlled charge with charging currents up to 1/3 C. For a battery with 1,200 mAh, a charging t ime of about 3-4 hours would be reasonable. In the charging command described below,
60
parameter 15 determines the battery voltage that is to be achieved by charging, before the preset
charging time starts and limits the charging, should other charging criteria not come into effect .
Therefore, it represents a margin of safety that should be kept as small as possible.
Attention: The timer-controlled charge limit is a solution that serves as a secondary battery
protection, since the charging status of the battery is unknown at the beginning of the charging
process, and charge-end criteria may not be recognized by the software.
10.2.5 M inus Delta-U Recognition (Voltage Reversal at the End of C harge)
When a NiM H battery is fully charged (end of charge), the battery voltage will start dropping
again, even though the charging current is still being supplied. This voltage drop is interpreted as
the end of charge. The charging current may not go below 300 mA for the voltage drop to be clearly recognizable. The charging voltage is recorded with the 10-bit A/D converter that is integrated in the µ-processor.
In order to eliminate the fluctuation of individual readings, multiple readings are averaged and added up to a 16-bit value. The interval between individual measurements is 2 seconds. The number
of values that are formed this way can be predetermined in parameter P3. It is used to define the
time delta-t, through which the drop is supposed to be dedicated.
10.2.6 Maximum Voltage at the Battery
This criterion is acquired by measuring the cell voltage. It protects the battery against destruction.
The value specified for the battery in use should be selected here.
10.2.7 Delta T / Delta t Recognition (Change of Temperature)
If the battery temperature T rises faster throughout the time t than specified in the parameter, (the
charging energy is completely converted to heat), the battery is recognized as full.
This criterion only comes into effect, when a preset battery voltage is exceeded.
10.2.8 M aximum T Recognition (M aximum Temperature at the Battery)
This criterion protects the battery against destruction. The value specified for the battery in use
should be selected here.
Sending the charge command <ES C> "r" p1 ...p15 will restart the charging process. Since this
command is part of the standardTINIT, charging is restarted with each reset, if charging voltage
is applied. The charging process will also be restarted, whenever the voltage drops below a defined minimum value (typ. for 1.2V / cell of the standard battery pack).
10.2.9 Restart of Charging Process with Connected Charger
Even, when the charger is connected, the printer may continue to work. Interim printing operation
will not interfer with the complete charging.
When the battery voltage drops below a minimum value set through the battery charge command, the charging process will start again.

battery type: P1:="1": Ni- M H charge (standard)
(battery type: P1:="2": Li-Ion charge). All other values are not
permitted or turn off the charging.
Timer controlled charge: 1 equals : 1/10h, i.e.
1 := 6 min, but 250 := 25 hours; default is 40:= 4h.
The charging time starts, when the charging voltage is
applied and the command is received, for example from the
TIN IT during reset, or when the battery voltage drops below
the value defined through p13.
Number of values that are used for the subtraction of the voltage delta-U. Default is p3=60.
This results in a measuring time of 60 x 2 s: = 2 min.
The lower the charging current, the higher this value should
be.
Number of recognitions with delta- U as a negative result, before the end-of-charge is determined from that.
Default is p4=1.
Indicates the voltage difference, from which the delta- U is recognized as a valid negative delta- U. 1 LSbit equals 0.671 mV
Default is p5=18 x 0.565V = 10mV.
Maximum voltage value. 1 LSbit equals : 39.782 mV
Default is p6=169.
This results in a maximum voltage value of
169 x 39.782mV = 6.72V .For 4 cells, this is equivalent to a
voltage of 1.68V/cell.
If the battery voltage (Vp) exceeds this maximum voltage value
as many times as stated in p7, the charging will be stopped.
Repetition counter for the exceeding of the maximum voltage
value set with p6. The maximum voltage value has to exceed
the value determined with p6 P7 times in a row, in order for
the end of charge to be recognized and the charging to be
stopped. Default is p7=1.
p8 is like p3 for the measurement of the temperature change.
p8 is the number of values determined in multiple measurements within 2 s in order to determine the temperature
change.
Default is p8=60. This results in a delta-T recognition measurement time of 60 x 2 s = 2 min.
p9 is like p4 for the measurement of the temperature change.
p9 is the number of delta-T recognitions (with p8:=60 within
2 min.), before delta-T is recognized as valid. Default is p9=1.
p10 is like p5 for delta-temperature difference.
1 LSbit equals about 0.01° C. Default is p10=64.
p10:=64 means that the acquisition interval is recognized as a
temperature change at the end-of-charge, if the difference in
temperature of 0.64° C (p10:=64) predefined by p10 is exceeded within the time determined by p8 (8:= 60 e.g. results in 2
min).
60
p11:
p12:
p13:
Maximum temperature value. Corresponds to p6 for temperature. The temperature is measured with an NTC resistor that
is soldered into the battery pack. p11 provides the maximum
temperature value. If this is exceeded p12-times at the battery
cells during charging, fast charging will be stopped.
For a 6.8K NTC, this estimation formula applies:
p11:=(60° C - T ma x ° C) / 0.6° C
The default setting is p11:=25, corresponding to
Tmax ca. 45° C.
Caution: High temperatures result in small and therefore
inaccurate readings.
Corresponds to p7 for temperature. p12 is the value for the repetition counter, at which an exceeding of the temperature is
recognized. Default p12=1.
p13 determines the charging start voltage for dropping voltage. 1 LSbit theoretically corresponds to 39.782 mV.
Standard is p13:=133. This corresponds to
133 x 39.782mV = 5.29V. For 4 cells, this corresponds to
1.2V/cell.
p14:
p15:
Trickle charge ratio.
After the end of the fast charge, this value determines the medium value of the trickle charge, if the charger remains turned
on.
1 LSbit corresponds to a ratio of 2s active time to 512s inacti
ve time.
Default is p14:=10. This means, that during a period of 512 s,
the 300 mA charging current is turned on for 10 x 2s= 20s. 20s
equal 3.9% of 512s. Therefore, the trickle charge current will
be about 12 mA, corresponding to 3.9% of the permanent
medium current.
p15 determines the minimum battery voltage. Below this
value, a charging time limit (shut-down after a preset
charging time) and the minus delta-U recognition will not be
active. Default is p15=140. Therefore, the value for 4 cells will
be 1 40 x 39.782mV = 5.57V beträgt.
11 Li-Ion Battery Charging Circuit (Option)
First, see Battery Charging Circuit (Software Control) General Information on page 40.
11.1 Attention! Special Hardware is Required for Li-Ion Batteries!
For some controllers, the hardware can be set up for one or two Li-Ion cells (see hardware manual).
During the charging of Li-Ion batteries, the controller stops the fast charge and switches to trickle
charge, as soon as one of the following conditions is met:
• maximum U recognition (a predefined cell voltage is exceeded)
• end-of-charge through timer
• maximum T recognition (specification of a maximum battery temperature)
11.1.1 Maximum U Recognition
When the cell voltage reaches a value of 4.1 V during the charging process, the Li-Ion battery is
recognized as full. This voltage is determined through a charging circuit that is specifically adjusted for charging Li-Ion batteries.
11.1.2 Maximum T Recognition (Maximum Battery Temperature)
should be selected here.

p3:
M aximum temperature value. The temperature is measured
with an NTC resistor that is soldered into the battery pack. p3
provides the maximum temperature value. If this is exceeded
p4-times at the battery cells during charging, fast charging
will be stopped.
For a 6.8K NTC , this estimation formula applies:
p3:=(60° C - Tmax ° C) / 0.6° C. Default setting is p3:=255
(without protection, if the Li-Ion battery does not have an NTC
for temperature control).
Caution: H igh temperatures result in small and therefore
inaccurate readings. Please contact us with your questions.
p4:
Repetition counter for Tmax exceedings.
The maximum temperature has to exceed the value p3 p4-ti
mes in a row in order to stop the charging process.
Default is p4=1.
11.1.4 End-of-Charge through Timer

11.2 Standard Settings for GeB E Battery Types
In some controllers that have a battery charging circuit, the charging process for 4x Ni- M H cells is
preset in the batch file TINIT. Parameter changes or the switch to charging of Li-Ion batteries has
to be performed at the factory in the flash of the µ-processor, or in the E E P R O M through the appropriate command. Please contact the GeB E service department for more information.
Fast and trickle charge are indicated through distinguishing flash patterns of the status LED.
Please refer to Status Messages on page 34.

11.3 Battery Test
Generally, the exact determination of the remaining battery capacity in mobile systems can only
be achieved through extensive measuring. It also represents information that is not really important to the user.
For the printer system, it is crucial to know, how high the currents may become during printing, in
order to enable failure-free operation. The internal resistance of the battery determines, which
currents can still be withdrawn, without the voltage dropping below the permitted terminal voltage
range for operating the system. The printer module has an interrogation command <E S C>"{"l m
n, that can specifically put load on the battery through the activated print head for test measurements. The readings collected by the controller are reported back subsequent to the interrogation
command through the serial interface. With this information and the knowledge about the battery
in use, in combination with the experience the host collected in charging and end-of-charge cycles (small user program), the remaining print capacity can be estimated the best.

12 Batch Files (Text Files)
12.1 The Concept of Batch Files (Text Files)
In the program memory of the µ-processor (flash memory), the user can manage batch files (Tx)
that can be retrieved by command. Practically all commands that the printer understands can be
filed there in data strings of a macro, and retrieved through the command <E S C>"t" [No]: = "Print
batch file [No.]". In place of this command, the command sequence from the batch file will be processed during the processing of the print buffer, as if it had been written into the print buffer
through the interface.
In the flash memory, batch file memories with special functions (like TIN IT, where the commands
for the initialization of the controller are filed) are available.
As an option, the controller can be equipped with a serial E E P R O M , which can also store batch
files, filed by the user himself.
E E P R O M s with memory sizes of 1 / 2 / 4/ 8 / 16 / 32, or 64 KB can be used. The standard is 8 KB.
The software checks, if an E E P R O M is available, as well as its size and content, and automatically
adapts to it.
If there are no batch files stored in the E E P R O M, the standard batch files from the flash will be
used. However, if there are batch files in the E E P R O M that are filed under the same names, they
will take precedence over the batch files in the flash.
Two separate blocks of batch files exist:
• Block 1 contains the batch files T0 through T9.
• Block 2 contains the batch files TIN IT, TA, TQ, TR, and TS.
12.1.1 Batch File Block 1: T0 ...T9
T0 through T9 can contain user-specific macros, logos, etc., but they also have special functions:
T0: The printout of batch file T0 can be initiated through the command "Print batch file no. 0" or
after R E SET. If during R E S ET, the feed key is held down for a longer period of time, the printing
of this batch file will start after about two seconds. By default, information about the printer is filed in T0. In addition, the printout of a service text or of the company logo may be triggered.
T1: Is retrieved during operation through the command <E S C>"t""1": = [Print batch file no. 1], or
through the SET key, which is available as an option.
A self test with character set, printer specifications, etc. can be placed in this batch file. At the
end of the command sequence of a batch file, the retrieval of another batch file can be placed.
T2-T9: Initially, these batch files have no special functions assigned to them.
Batch files TIN IT and T0 through T9 can be changed by the user in the E E P R O M at any time. Loading commands are available for this purpose.
12.1.2 Batch File Block 2: TINIT, TA, TQ, TR, TS
12.1.2.1 TIN IT
TINIT: Works as initialization macro. After a power-on R E SET, watchdog R E SET, or software
R E SET, TINIT is called at the end of the software initialization, so the commands for changing the
parameters that are stored in it are sent to the printer. If the TINIT is filed in the E E P R O M, the
commands stored in it take precedence over all previously set parameters. Since the TINIT in the
E E P R O M can be written by the user himself, it enables him to determine the printer initialization. If
for example the printer is supposed to print in data mode with double height and bold, the corresponding commands are entered in the batch file TINIT. After the R E S ET, the controller will first
process these commands, thereby changing its initialization.
12.1.2.2 Example: Basic Setting of the Controllers
The basic settings that are put into effect in the initialization program of the controllers (they are
not entered in the TINIT) correspond to the following instructions for some controllers: <E S C> "A";
<E S C> "D" "0"; <E S C> "H" "0"; <E S C> "I" "0"; <E S C> "L" "0"; <E S C> "M" "0"; <E S C> "N" 0 0;
<E S C> "P" 1; <E S C> "S"0; <E S C> "W" "0". If these settings are to be changed after a R E S ET,
the appropriate commands have to be added to the TINIT (by the user in the E E P R O M).
60
12.1.2.3 TA, TQ, TR , TS
These batch files work like the batch files T0-9, but they can neither be erased nor rewritten. Contents are firmware status, serial numbers, etc.
TA: Contains commands that initiate the H EX-dump mode, and can only be programmed by
GeB E.
TQ, TR, TS: These batch files are filed in the flash memory of the µ-controller chip. They can only
be programmed at the factory (for firmware status, serial number, etc. ), and are not meant for general use.
TQ contains the firmware nomenclature: for example "GeB E G E -3055".
12.1.3 Storage Space for Batch Files
The GeB E batch file concept represents a type of file system within the printer memory.
The E E P R O M is managed by adding newly entered or overwriting batch files to the occupied storage spaces. Erasing single batch files is not possible. Batch files can be programmed independently, but they can only be erased by block (block 1 or block 2).
Block 2 in the E E P R O M can be protected against erasing via software (please inquire).
In this case, a quarter of the total memory is available for block 2 at any time. Otherwise, 200
bytes are assigned to block 2 from a 1K E E P R O M , and 456 bytes from all larger types. For the
programmable batch files, the following capacities remain:
From a 32 KB E E P R O M , 24,424 = $5f68 bytes are available,
from an 8 KB E E P R O M, 5,992 = $1768 bytes are still available.
For the filing of graphic data in a batch file, it is recommended to use P CL compression, because
it allows much larger graphics to be stored (ap. 1:3), especially, if they contain a lot of zeros ($00)
in the pure pixel image. If the OP-Menue® is used, the space for block 2 is reduced by 228 bytes.
If the OPD menu is used, the space for block 2 is reduced by 228 bytes.
12.1.4 Help with Unknown Interface Parameters
If a controller gets "out of control" during communications due to program errors or other initialization problems, it can be addressed as follows: The special setting of the solder bridge combination Br1, Br2, Br3 closed and Br4 open allows a by-pass of the TINIT. With this setting, it is always started off serially with 9,600 bauds, 8 data bits, 1 stop bit, and no parity bit. This way, communication with the controller is still possible and the E E P R O M can be reprogrammed, even if the
interface parameters are unknown.

Send string through the serial interface to the host:
This command is entered in a batch file with the data.
It can be used, for example, to inquire serial numbers entered in TS.
Example:
The serial number 1234567890 is entered in the batch file TS with the
transmission command as < E S C> n [10] [1234567890].
With the command <E S C>"T" "S", the batch file TS is retrieved, and the
command < ES C> n [10] [1234567890] it contains is processed by sending the text string "1234567890" (serial number) back to the host.
This command is similar to the command "Send synchronizing character",
except that it does not wait for the synchronization, and a complete string
can be sent out through the serial interface.

12.2.2 Readout of the Available Memory Space in the E E P R O M
With a command, the user can check, if there is enough memory space available in the E E P R O M
before programming. If a batch file is reprogrammed under the same name, the original content
will not be erased, but remains in the memory unused. Erasing in the E E P R O M can only be done
through the command <E S C> "u"... . See page 49.

12.2.3 Readout of Batch Files
With this command, the content of any batch file can be read out through the serial interface.
Please note:
This command should NOT be given, if the <XON>/<XOff> protocol is used.
<X ON>/<XOff> characters that are in the file (e.g. in graphics) are transferred uncoded.
When the <XON>/<XOff> protocol is activated, the printer buffer should not be in the <XOff > state,
before this command is sent, and no other data should be sent to the printer, while batch files are
being read out, in order to prevent an <XOff> character from entering the data stream. Otherwise,
the <XON>/<XOff> characters that were generated by the printer may be interpreted as part of the
file.

The dummy byte n can have any value (essential for programming reasons). After this command, the data in the file is transmitted through the
serial interface:
The controller sends the length values lh and ll as 4 AS C II characters that
are encoded as 2 hex nibble, and that define the file length.
1B 76 38
"m" n
The command for reading out batch files must not be part of a batch file itself. In this case, as a response to an unvalid batch file no., or if an EEP R O M file is not programmed, the letter sequence "XX XX" will be sent
instead of the 4 hex digits.
Readout of the FLASH file m:= {"0","1", ....,"9","Q", "R", "S","@"}
(same function as ES C "v" "7") For description see above.
Attention:
If batch files were filed several times in a row under the same file name, only the file that was stored last can be read. The access to previously stored contents is lost.
The files that are filed in the FLAS H of the µ-processor, however, can be read at any time with the
command E S C "v" "7" <Nr> D U M M Y, even if a batch file with the same name was programmed in
the E E P R O M .
12. 2 .4 Progra mm ing and E rasing B at ch Files

can be programmed several times in a row without erasing the previous
version. Always the last version is active. Reorganization of the memory,
however, does not occur. With the next programming, the memory space
that was used for the previous programming is lost until the next erasing.
255 x [xh] + [xl] is the number of data bytes to be loaded (without the command sequence). (Data) is a data string that contains the number of data
bytes calculated from xh and xl.
The writing speed is about 200 bytes/s.
Program the batch file TINIT :
For a description, see <ES C> "s"(no) .....
Attention:
By default, the TIN IT contains important parameters for setting the serial
interface, the battery charge, the power-down, etc., that are not automatically adopted, when the E E P R O M is programmed.
Therefore, the user should copy the old parameters (from the FLAS H, or
from a TINIT that GeB E had previously programmed in the EE P R O M), when
he creates a new batch file TINIT, and program them into the E E P R O M,
supplemented by the required commands.
Commands regarding the interface parameters should be inserted before
the command <ESC> "]" $00 $00 to release the transmitter. This way, messages after the reset will already be sent with the new settings.
Erase batch files 0 - 9.
Batch files T0 - T9 can only be erased together.

13 Error Diagnostics
13.1 General Information about Error Diagnostics
Error diagnotics are no substitute for a complete functional test, like the one that is performed before each delivery at the GeB E test department. However, the diagnostic aids described below often prove to be helpful, especially for the initial operation of a printer, or, when a driver program
has been written, and the respective commands are being sent to the printer.
Also see "Error Detection" in the operating manual of your device.
The following diagnostic help is available:
• Self test printout during power-on after R E S ET through the F E ED key
• Hex-dump mode
• Error detection for standard errors (see hardware manual)
• Battery test; refer to the Battery Test chapter on page 45
• Error messages while starting batch files: Please refer to Error Codes for Processing Batch Files
on page 49.
13.1.1 Self Test, Batch File T0
By triggering a self test printout, when the power supply is turned on, the correct functioning of
the addressed interface can not be tested. However, if the self test runs error-free, one can assume that the internal µP system is running faultlessly and the printer should be able to print data, if
it was able to receive it through the respective interface.
For the self test printout, batch file T0 is processed and printed, if the feed key is held down for
longer than 2 s during the reactivation process. T0 can also be filed in the E E P R O M and be changed by the user. Refer to Commands for M anaging Batch Files on page 47.
13.1.2 Test Printout, Batch File T1
If the OFF/NEXT key (test key) is pressed during operation, batch file T1 will be processed. The µP flash contains the formfeed command for the formula modus. Additionally the character set and
other information may be stored in this batch file, for example the retrieval of the batch file containing the software version number.
13.1.3 Turn Off Printer, Batch File T2
By holding down the OFF/NEXT key for more than 3 seconds during operation, the processing of
batch file T2 is initiated. In the batch file T3 located in the µ- P flash, the command for power-off is
stored (after one second). Therefore, the OFF/N EXT key can be used as the OF F button for the
printer (controller with power-off mode).
13.1.4 Hex-Dump Mode
The hex-dump mode represents a tool that allows certain diagnostics regarding sent data without
having it interpreted by the software of the printer controller. The diagnostics let the user draw
conclusions on whether the recieved command sequences are in accordance with the commands
intended. In hex-dump mode, the bytes transmitted from the host system to the printer are printed as hexadecimal values and AS C II characters, in order to recognize independently from interpretations happening in the parser, which data sequences are received by the printer. This allows
the detection of communication errors, which can be very helpful for servicing the printer. For
command retrieval, refer to page 51.
13.1.4.1 M anual Starting and Stopping of the Hex-Dump M ode
The printer will switch to the hex-dump mode, when the feed key is held down for at least 3 seconds during power-on and no paper is detected at the entrance to the printer (open lid for the
plastic housing).
While the printer is in H E X-dump mode, a power-down (sleep mode or power-off mode) is prevented. In order to leave this mode, the printer either has to be turned off completely (cut off power supply) or a hardware R E S ET has to be triggered. Some controllers leave the H EX-dump
mode, if the paper is removed again, after it was detected, and the feed key is held down for at
least 3 seconds afterwards. After the H E X-dump mode, the printer is reinitialized by processing
the TINIT.

Attention:
13.2 Assistance with Errors during the Programming of Batch Files in the E EP RO M
The solder bridge combination Br1, Br2, Br3 closed and Br4 open has the serial interface initiated
with 9,600 baud, 8 data bits, 1 stop bit, and no parity bit instead of retrieving the TIN IT after a
R E SET. This prevents potentially faulty interface initialization in the case of unknown values and
flawed programming in the E E P R O M . The user can communicate with the controller, erase the
E E P R O M contents, if necessary, and then reprogram.

15.1 Real Time C lock with Alarm Register
15.1.1 C lock, Summary of Functions
For some controllers, an optional clock chip is available, or an external clock module is added
through the S P I- B U S. The clock has a resolution of 1s, and can be set and read through commands.
15.1.1.1 Alarm Register
Essential for the function within the printer concept is the alarm register function that is installed in
the clock. It allows the printer to be activated at a preset time.
15.1.2 C ommands to the C lock
Available commands concerning the clock are:
• Set date/time
• Set alarm
• Read clock through the serial interface
• Print data and/or time
15.1.2.1 Setting the Clock through the O P D- M enue®
The clock can also be set manually with two keys through the settings menu.
15.1.3 Commands for Setting and Reading the C lock Through the Interfaces

This command automatically activates the alarm. It can be turned on
or off with the command Activate/Stop alarm.
Once the alarm time runs out, the current time is automatically read
from the clock, and the period parameters are added and saved as
the new alarm parameters in the alarm register of the clock.
If instead of a valid value, the parameter is specified as 0xFF, there will be no
verification.
If for example, for < alarm-weekday> and < alarm-hours> 0xFF is entered, an
alarm will be triggered each time the values for seconds and minutes correspond. <ESC> "c" 04 03 24 FF FF

Function
Print command for the clock.
The individual bits of the flag bytes have the following meaning:
d0 =1 := print seconds
d1 =1 := print time
d2 =1 := print date
If, for example, d0 of the flag byte is set to 1, the seconds field is printed
as follows: 03
If the date and the time are to be printed, and d1 and d2 of the flag byte
are set, 2 spaces are printed in between.
d3=1 := print week-day
d4=0 := use English terms
d4=1 := use German terms
d5, d6 d7 user-defined
The command for printing the clock is ignored, if the appropriate hardware (clock chip) is not recognized. This way, batch file T0 can always
contain a command to print the clock data without causing problems, if
the additional circuit board is not available.
The print attributes that are currently in effect apply.
The complete output format looks like this:
2 11.08.04 17:29.03 or 2 08/11/04 17:29.03
Leading zeros are not disabled.
If d3 of the flag byte is set, the day of the week is printed, followed by a blank.
If the bit is not set, none of these characters are printed.
If d2 of the flag byte is set, the current date is printed in the following format:
22.08.04 or 08/22/04
If d1 of the flag byte is set, the time is printed in the following format: 17:29
If d0 of the flag byte is set, the seconds are printed in the following format: .03
Attention: This command does not contain an automatic line feed to allow the
printing within one line (with subsequent text).
15.2 Periphery - M agnetic C ard Reader
The magnetic strip can contain up to three tracks with serial data. The recording density and the number of bits per character differ from one track
to the next in accordance with IS O 3554. They determine the maximum
number of characters that can be saved on each track.
For track 1, the maximum number is 79, for track 2 maximum 40, and for
track 3 maximum 107 characters, including the start and stop characters.
In accordance with the norm, track 1 and 2 are only read during operation. Track 3 is the only one that is also used for recording.
Operation:
After the swiping of the card, the LED lights up for about 2 seconds, if the
card was read correctly. If an error occured, the LED will flash rapidly 6 times.
While the LED is on, another reading process is not possible. After the
LE D has gone out, the internal buffers are being prepaired for a new reading process, waiting for another card to be swiped.
<ESC> M <No T1> <Status T1> <Data T1> <No T2> <Status T2> <Data
T2> <No T3> <Status T3> <Data T3> <Checksum>
No T1:
Binary number of characters in track 1. The status byte is not included.
If the track is empty, this byte is a binary ZERO.
Status T1:
Status byte of track 1. The ASCII characters '0' - '9' are used.
'0': no error, data of track 1 valid.
'5': no data in track 1.
'6': buffer overflow (more than 79 characters)
'7': no end character detected in track 1.
'8': parity error occured in track 1.
'9': LRC error occured in track 1.
In case of an error, the number of characters (parameter <No T1>) is set
to zero, and no data is transmitted. Code '5' means that this track does not
exist.
Data T1:
Data of track 1 converted to ASCII. The number of characters corresponds
to the parameter <No T1>.
No T2:
Binary number of characters in track 2. The status byte is not included.
Status T2:
In case of an error, the number of characters (parameter <No T2>) is set
to zero, and no data is transmitted. Code '5' means that this track does not
exist.

15.3 Periphery - Second Serial Interface ( Planned !)
15.3.1 The AUX UART
External peripheral devices with a low data output, such as a bar code scanner, can be connected to this serial interface.
The AU X UART interface can be equipped with an R S232, a 3.3 V, or a 4.5 TTL interface.
15.3.2 Configuration of the UART
<E S C> "Z" 00h < baud rate> <flag bytes>
(Configuration and meaning of the parameters correspond to the setting of the serial interface in
the NEC)
The default setting is 96, n, 8, 1
Data from the host to the external device (for example bar code scanner)
<E S C> "Z" <numberl><data><CsmHigh><CsmLow>
Data:
as described in the manual of the bar code reader
- max. block size is 255 + 2 bytes checksum
- the first byte represents the data length (without checksum / max. 0xff)
Since the data is secured with its own checksum, an additional checksum is unnecessary.
Data from external device (for example bar code reader) to the host
<E S C> "Z" <number><data><CsmHigh><CsmLow>
Data: see description above.
